PeepholeOpt: Try to constrain uses to support subregister (#161338)
This allows removing a special case hack in ARM. ARM's implementation
of getExtractSubregLikeInputs has the strange property that it reports
a register with a class that does not support the reported subregister
index. We can however reconstrain the register to support this usage.
This is an alternative to #159600. I've included the test, but
the output is different. In this case version the VMOVSR is
replaced with an ordinary subregister extract copy.
